Duck manure organic fertilizer and manufacturing method thereof

Abstract

The invention discloses a duck manure organic fertilizer, which comprises duck manure, plant straw, potassium chloride, ammonium phosphate, borax, zinc sulfate heptahydrate, humic acid, and compositemicrobe. The invention also discloses a manufacturing method of the duck manure organic fertilizer. The manufacturing method comprises the following steps: step one, collecting weeds and branches of crops, adding a fermenting agent, and mixing; step two, collecting duck manure, reducing the water content of the duck manure, adding composite microbes into the duck manure, and carrying out fermentation to obtain barnyard manure; step three, paving fermented plant straw, potassium chloride, ammonium phosphate, borax, zinc sulfate heptahydrate, humic acid, and composite microbe on the barnyard manure; step four, preparing a deodorizing agent and a water-retaining agent; step five, stirring organic fertilizer raw materials paved in the step three, and spraying the deodorizing agent and the water-retaining agent at the same time; and step six, keeping on fermenting the organic fertilizer, and then carrying out grinding, granulating, drying, and cooling in sequence to obtain a finished product. The organic fertilizer can supply more comprehensive nutrients for plants, and added boron and zinc can promote the growth of plants.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizer preparation, and in particular relates to a duck manure organic fertilizer and a preparation method thereof. Background technique [0002] Extensive use of chemical fertilizers is costly and seriously pollutes cultivated land and crops. Duck manure is composed of undigested and absorbed parts of the feed, metabolites in the body, gastrointestinal mucosal exfoliation and secretions, intestinal microorganisms and decomposition products, etc. Fresh duck manure is rich in plant nutrients, of which N is 1.64 %,P 2 o 5 3.53%, K 2 O is 1.02%, total nutrient N+P 2 o 5 +K 2 O is 6.19%. However, the soluble phosphorus and potassium that plants can absorb and utilize in fresh duck manure is very little, and direct use will cause root rot and burn seedlings. The duck manure fermentation process is the process of using microorganisms to decompose and transform duck manure. It is the most eff...

Problems solved by technology

However, there is very little soluble phosphorus and potassium that plants can absorb and utilize in fresh duck manure, and direct use will cause root rot and burn seedlings, etc.

The duck manure fermentation process is the process of using microorganisms to decompose and transform duck manure. It is the most effective way to recycle duck manure. By mixing appropriate amounts of phosphate and potassium fertilizers into the fermented duck manure, it can effectively solve the problem of organic fertilizers. Insufficient phosphorus and potassium elements in the medium, but organic fertilizers are prone to grow a large number of plant-rot pests during the fermentation process, and direct application of untreated organic fertilizers will easily lead to the occurrence of plant diseases and insect pests; in addition, ducks are waterfowl. Its food contains a lot of protein, so its feces are relatively compact, which is easy to inhibit the activity of fermentation bacteria, which is not conducive to fermentation. At the same time, duck manure has a heavier odor than cattle and sheep manure. If it is not deodorized accordingly, it will be extremely harmful The environment that greatly affects the production, storage and application of organic fertilizers

The structure of the fermentation tank in the traditional fermentation method is open, and the dumping of materials pollutes the environment and volatilizes nutrients
